Abstract: Optical apparatuses for enhancing scotopic vision. The optical apparatuses include a lens. In some instances, the optical apparatuses include a frame. The lens has an optical power adapted to focus light specifically under scotopic vision conditions in a user's eye. In some examples, the optical apparatuses include a spectral filter adapted to allow transmission of selected wavelengths of light through the spectral filter.

Abstract: A highly visible overlay system includes contrasting visible elements configured to define an image overlay, a first portion of the visible elements comprises opaque elements having high contrast with bright areas of a field of view, and a second portion of the visible elements comprises illuminated elements having high contrast with darker elements of the field of view. The system may capture an image of a target scene for display and include a processing component configured to construct the plurality of contrasting visual elements in accordance with a visual acuity factor, and generate an electronic overlay constructed of the contrasting visual elements. The overlay may comprise a reticle formed on an optical element of a scope, including nonilluminated opaque portions and illuminated portions illuminated by a light source.

Abstract: An axial divergent section slot nozzle for an engine is provided. The nozzle has a plurality of spaced apart divergent flaps, at least one device for moving the divergent flaps to change a cross sectional area of the nozzle in a throat region, and a bridge member positioned intermediate adjacent ones of the flaps. The bridge member includes a bridge bracket and a sealing element joined to the bridge bracket. The sealing element has an upper surface. The bridge bracket has a lower surface which diverges from the upper surface of the sealing element. In a preferred embodiment of the present invention, the bridge bracket has a shape which allows variable slot size depending on nozzle throat jet area.

Abstract: The invention relates to a set of golf clubs employing a two-piece golf club shaft wherein the lengths of the first and second shaft members vary as the loft of the golf club varies. The set of clubs includes a plurality of golf clubs having varying lofts extending from lower loft golf clubs to higher loft golf clubs, wherein each golf club includes a club head and a shaft having a distal end and a butt. Each shaft includes a first member having a first end located at the butt end of the golf club shaft and a second end positioned slightly short of the distal end of the golf club shaft. A second member is secured to the second end of the first member. The second member extends from the second end of the first member to the distal end of the golf club shaft and includes a first end securely coupled to the second end of the first member and a second end which is ultimately secured to a golf club head.

Abstract: A golf club head for hitting a golf ball toward a target has a directional tendency to launch the golf ball in a selected direction. Basic embodiments include a club head having an asymmetric ball striking face such that one side of the face, as measured from the center of the face, has a first bulge radius and the other side of the face has a second bulge radius. The club head assumes a directional tendency in the direction toward the smaller bulge radius. Other embodiments of club heads with a directional tendency have a striking face with a bulge radius apex shifted either right or left of the center of the striking face such that a club face with the bulge radius apex to the left results in a right directional tendency and a club face with a bulge radius apex to the right results in a left directional tendency. Further embodiments of a club head may include a combination of a shifted bulge radius apex and a different radius on each side of the center of the striking face.

Abstract: An apparatus and a method for embedding conductors in a structure having a signal distribution function associated therewith such as a vehicle instrument panel are disclosed. The apparatus includes an embedding tool which can be positioned in three dimensional space to embed conductors in non-planar surfaces. A method for such embedding is also disclosed.
